As the crank armsl5 and '17 are rotated in the construction illustrated, there Will be nomovement of the outer end of the rake shaft 13 and therefore anybreakage due to the twisting of` this shaft is avoided by the use ofmyimproved construction.

ln view of the fact that the spider 30 is substantially the only elementchangeil in position by the adjustment of the rake' teeth, itf will bereadily understood .that the Amanipulation of these rake teeth is a verysimple operation and requires very little effort on the part of theoperator.

it is evident that there may be various modifications ofthe invention asparticularly herein shown and described, and it `is my intention tocover all such modifications which do not involve a departure from thespirit and scope of the invention as set forth inthe following claims.-
